If you have to ask how much, you can’t afford these two lenses. You could buy a car for the price of each of these.
The Canon EF 600 mm f/4L IS II USM and EF 500 mm f/4L IS II USM super-telephoto lenses are said to deliver incredible image quality at all apertures for professional photographers and filmmakers. They replace lenses Canon introduced 11 years ago, new versions based on feedback from professionals. Both have experienced a drastic weight reduction making them lighter and more durable than their predecessors. Both lenses also achieve a higher level of image quality through the incorporation of two fluorite optical lens elements which help to minimize chromatic aberration and eliminate colour blurring around the edges of the subject. Both new lenses offer improved Image Stabilization, providing the equivalent shutter speed of approximately four steps faster in addition to enhanced durability and operability through thoroughly re-designed optical and mechanical components.
The optical formula of each new lens was re-designed to include two fluorite elements instead of one fluorite and two Ultra-low Dispersion (UD) glass elements. Contributing to the overall weight reduction are increased use of magnesium alloy, use of titanium and a smaller and lighter Image Stabilizer mechanism.
The new super-telephoto lenses also include a nine-blade circular diaphragm for a smoother appearance in areas outside the depth of field of the main subject. In addition, Canon’s SWC (Subwavelength Structure Coating) is applied to four internal groups in each lens to improve resistance to flare and ghosting.
These lenses also are treated with Canon’s new fluorine anti-smear lens coating. The fluorine layer is highly oil- and water-repellent so that any oil smears or water droplets on the lens can be wiped off quickly and easily, without the aid of solvents, using a soft dry cloth.
A new low-friction stabilizer mechanism is not only more efficient than the previous design but also smaller and lighter. Other enhancements to the IS systems of both new super-telephoto lenses have enabled quieter operation.
Canon has developed a third Image Stabilization mode option for its super-telephoto EF lenses. IS mode 3 is designed to provide professional sports and wildlife photographers with greater tracking flexibility. When mode 3 is selected, the Image Stabilization effect will not occur until the shutter is pressed, making the viewfinder image more natural in appearance while tracking a subject. In mode 3 when the shutter button is pressed halfway, the lens will begin detecting camera or lens movement and only during exposure, when the shutter is fully depressed, will the Image Stabilization engage.
Helping filmmakers achieve smoother and more appealing focus shifts when filming on EOS DSLRs, Canon has included a new Power Focus (PF) mode. This allows manual rack focusing to be operated smoothly by turning a playback ring normally used for the focus preset function. Both low-speed and high-speed focus shifting are available.
Additionally, a new security slot attachment has been included on both of the new super-telephoto lenses to allow a wire-type security lock to be easily affixed, a great safety feature for professionals shooting from high vantage points above arenas and crowds. (Ouch!)
The 500 mm lens is 18 percent lighter, now 112.5 oz., with the 600 mm lens down 27 percent to 138.3 oz.
The Canon EF 500mm f/4L IS II USM lens is expected to be available in May for an approximate retail price of $9,999. The Canon EF 600mm f/4L IS II USM lens is expected to be available in June for an approximate retail price of $12,599.
